1 General Information
1.1 Important Regulatory and Safety Requirements
Operation
Before operating the boiler, make sure you fully understand its method of operation. Your heating contractor should always perform the initial start-up and
explain the system. Any warranty is null and void if
these instructions are not followed.
Working on the equipment
All personnel working on the equipment or the heating system must have the proper qualifications and
hold all necessary licenses.
Ensure main power to equipment, heating system,
and all external controls has been deactivated. Close
main oil or gas shut-off valve. Take precautions in
all instances to avoid accidental activation of power
during
service work.
Dangerous conditions
– Deactivate main power immediately.
– Close main gas or oil shut-off valve.
Keep all literature in a safe place at the installation
site. Contact Viessmann for additional copies.
Incomplete combustion and
)
Regular maintenance and service
The entire heating system must be cleaned and serviced on a regular basis by a qualified heating
contractor or service agency to ensure reliable,
energy-efficient, and environmentally
friendly operation.
The build-up of soot on the heat exchanger raises
the flue gas temperature and reduces efficiency.
Indirect-fired domestic hot waterstorage tanks (if installed) must be serviced within two years (at most)
of the installation date, and regularly thereafter (see
Service Schedule starting).
For an overview of scheduled service procedures,
please see section entitled “Service Schedule”.
Flue gas smell
– Deactivate heating equipment.
– Open windows and doors.
– Inform your heating contractor.
Combustion air and ventilation air openings
Ensure that combustion air openings and ventilation
air openings in the mechanical room are open.
Technical information

Keep boiler and boiler room clear and free from
combustible materials, gasoline and other flammable
vapors and liquids. Do not obstruct the flow of
combustion and ventilation air. A qualified heating
contractor must perform all inspection, maintenance
and service.
Carbon monoxide can cause severe personal injury
or loss of life.
Therefore, carbon monoxide detectors that are in
compliance with a nationally recognized standard
(e.g. ANSI/UL 2034-2002, CSA 6.19-01) should be
installed and maintained in buildings that contain
gas-burning equipment.
Note:
Viessmann does not test any detectors and makes
no representation regarding any brand or type of detector.
Important to know
Do not use this boiler if any part has been under, or
exposed to, water. Immediately call a qualified heating contractor to inspect the boiler and to replace
any part of the control
system and any gas control which has been under,
or exposed to water.
Carbon monoxide
The U.S. Consumer Product Safety
Commission strongly recommends the installation of
carbon monoxide detectors in buildings in which
gas-burning equipment is installed.
Carbon monoxide (CO) is a colorless, odorless gas,
which may be produced during incomplete combustion of fuel and/or when the flame does not receive
an adequate supply of combustion air.
For safe operation
We recommend that you frequently:
- Check for debris which could obstruct the flow of
flue gases. The vent or chimney must not be
blocked. Ablocked or partially blocked vent or chimney can cause flue gases to leak
into the structure. Flue gases leaking into the house
can cause injury or death. Blocked or partially
blocked chimneys must have the blockage removed
by a qualified heating contractor.
- Check pressure gage for correct system (water)
pressure. Check for water on the floor from the discharge pipe of the pressure relief valve or any other
pipe, pipe joint, valve or air
vent.
- Check for moisture, water, or appearance of rust
on the flue gas pipes, their joints as well as vent
dampers, or side wall vent terminals
(if so equipped).
- Ensure that nothing is obstructing the flow of
combustion and ventilation air and no chemicals,
garbage, gasoline, combustible materials, flammable
vapors and liquids are stored (not even temporarily)
in the vicinity of the boiler.
- Do not allow unsupervised children near the boiler.
Service/inspection of the boiler and the system is
recommended once a year. Maintenance, service
and cleaning are specified in the Installation Instructions.

Shut off the water supply to the building, drain
the water pipes and add antifreeze for potable water
to drain traps and toilet tanks. Open faucets where
appropriate.
Or…
Have someone check the building frequently during cold weather and call a qualified service agency
if required.
afety (continued)
Or...
Frozen water pipe hazard
Install a reliable remote temperature sensor that
will notify somebody offreezing conditions within
the home.
Failure to protect against frozen pipesafety
If you notice fire coming from the appliance, call the
fire department immediately! Do not attempt to extinguish the fire unless qualified to do so.
Installation area conditions
Your heating boiler is designed to provide
a warm and comfortable living environment. It is
NOT designed to ensure against freezing of water
pipes. The boiler is equipped with several safety devices that are designed to shut down the boiler and
to prevent it from
restarting in the event of various unsafe
conditions.
If your boiler remains off for an extended period of
time during cold weather, water pipes may freeze
and burst, resulting in extensive water damage and
conditions in which mold could grow. Certain molds
are known to cause respiratory problems, as well as
to pose other serious health risks. In case of water
damage, immediate measures should be taken to dry
out affected areas as quickly as possible to prevent
mold from developing.
If your home will be unattended for anextended period of time during cold weather, you should...
Ensure ambient temperatures are higher than
50°F / 10°C and lower than 104°F / 40°C.
Prevent the air from becoming contaminated by
homogenate hydrocarbons (e.g. as contained in
paints solvents or cleaning fluids) and excessive
dust (e.g. through grinding or polishing work).
Combustion air for the heating process, and ventilation of the boiler room must be free of corrosive
contaminants. To that end, any boiler must be installed in an area that has no chemical exposure.
The list to the right indicates the main, currently
known sources.
Avoid continuously high levels of humidity (e.g.
through frequent drying of laundry).
Never close existing ventilationopenings.

2 Important Information
RISK OF INJURY:
If the doors are open during operation, sparks or flames
could leap out.
2.1 Safety instructions
When carrying out work on the heating system, such as
cleaning and maintenance, wear appropriate protective
equipping when required.
There is a danger of getting injured through: burning,
knocking against corners and edges, crushing in moving
parts and noise.
Mains supply: 120V or 240V/1/ and 208V/3/ 60Hz
Equipment for dissipating excess heat
A competent specialist should examine the operational reliability of the thermal run-off safety valve annually. The
safety heat exchanger must not by any means be used as
an operational heat exchanger.
Seals
Doors
For the functioning and controllability of the burner, it is
important that no unwanted air can leak in, entering unchecked through leaky spots.
The doors and lids have to shut tight − any damaged seals
must be replaced immediately. Tighten the retaining
screws and handles snugly.
For safety keep firing and ashpit doors tightly closed.
Operation, cleaning & maintenance
In a risky situation, the PYROT can be disconnected from
the electrical mains at all the leads by the master switch
on the control cabinet
CAUTION
FIRE HAZARD:
The boiler must never be operated with the doors open!
Any burning bits that escape could start fire.
2.2 Excess temperature/power failure
CAUTION
DANGER OF THIS SUDDENLY GOING UP IN FLAMES:
Do not open the doors or lids on the boiler plant!
-
Switch on additional heat loads.
The flue gas fan goes out of operation.
The temperature-limiting safety switch triggers.
The valve for the thermal run-off safety valve opens at
approx. (95°C) 203° F. The excess heat is conducted
off into the channel.
Bear in mind that only if operated and maintained properly
can even the best of products fulfil their functions well,
doing so for a long time and free of malfunctions.
Compliance with the "Cleaning" section is mandatory!
2.3 Low water/excess water pressure
Possible causes:
1. Low water: Leakage in the heating system.
2. Excess water pressure: The expansion tank not
functioning.
In either case, should the boiler examined by a competent
heating constructor.
Unlock this malfunction with either the reset button for
the water level control system or for the overpressure
monitor, and by pressing the OK key on the control panel.
If the temperature-limiting safety switch (FHL) has triggered, then it has to be manually unlocked. The FHL is
situated at the top of the boiler.
To reset, unscrew the black cap and press the button.
NOTE: Only as of a temperature of approx. (70°C) 158°F
resetting is possible.
Possible causes for excess temperature:
- Incorrect setting on the control module.
- Defective component of the system (pump or valve).
- Sudden drop in output to zero. The feed auger still has
to be emptied. The heat yet produced by this can result in surplus temperature. Activate "DISSIPATE
SURPLUS HEAT" function!
12
2.4 A fire hazard
With insertion-type firing systems, the conveying route
creates a connection between the silo and the burning material in the boiler plant.
With the PYROT insertion-type heating boiler, the feed auger is also the metering auger, and is thus always filled up
with material during operation There are various safety
devices provided to prevent burn-back.
Temperature sensors:
By means of temperature sensors on the feed auger, in
case of excess temperature the loading to the feed auger
is interrupted, and the feed auger's material is inserted
into the combustion chamber.
Slide valve (optional):
This closes in case of a standstill, danger of burn-back or
power failure (spring return motor).
valve (optional):
Instead of a slide valve, in silos with pressurisation.
Drop-off route:
A vertical drop-off section interrupts the connected line of
burning material.
Fire-extinguishing system (option):
This system, which functions independently of the electrical power, brings about a flooding of the material to be
burned that is located in the feed auger. The activation
temperature is approx. (95°C) 200°F.
(30 cm) 1ft above the articulated arm or over the
spring-mounted plates. As soon as the articulated
arms or spring-mounted plates have retracted through
a request for material, the refilling can be continued.
Heating out of operation:
- If the articulated arms or spring-mounted plates are still
covered by fuel, refilling can be carried out immediately.
- If the articulated arms or spring-mounted plates are no
longer covered by fuel, fill the silo evenly to approx.
(30 cm) 1ft above the articulated arm or over the
spring-mounted plates. Then activate the "SILO FILLING" function. To do so, press the LOADER SYSTEM
key (F4) and then the left arrow key (<). Then select
"YES" and confirm with "OK". Wait until the articulated arms or the spring-mounted blades go under the
cup washer, and then finish evenly filling the silo. The
"SILO FILLING" function brings about the filling of the
fire box.
NOTE: The "SILO FILLING" function cannot be activated
until the heating system has been out of operation for one
hour.
Moving floor conveyor

2.5 Wood fuels, minimum requirements
The PYROT is only suitable for incinerating the fuels listed
in Spec Sheet 1010 "Minimum Requirements for Wood
Fuels" (see supplement).
Fuel can be refilled automatically.
Funnel extraction system
-
It is mandatory that the heating system be in operation!
2.6.2 By blowing in
If different fuels are used, Viessmann will not assume any
liability for the functioning or service life of the boiler
plant. Refer to the "Warranty" section in the General
Terms and Conditions of Delivery.
-
Born wood only
Do not use chemicals or fluids to start fire.
Do not burn garbage, gasoline, naphtha, engine oil, or

2.6 Filling the fuel storage unit
When storage facilities for wood are required, the wood
should be kept at least (1.5m) 5ft from the heating appliance.
2.6.1 By dumping
The heating system has to be out of operation (danger of
excess pressure or negative pressure caused by the action
of blowing-in). Filling procedure as described in section
2.6.1.
2.7 Correcting malfunctions in the feed systems
The cause of motor malfunctions in feed systems is usually clogging by large pieces of wood or foreign matter.
CAUTION
DANGER OF INJURY:
Always turn off the master switch before carrying out any
repair of a malfunction on feed systems and every time
before a maintenance lid is opened or a protective device
is removed!
Rotary sweep extraction and spring-operated extraction
Heating system in operation:
- If the articulated arms or spring-mounted plates are still
covered by fuel, refilling can be carried out immediately.
- If the articulated arms or spring-mounted plates are no
longer covered by fuel, fill the silo evenly to approx.

4.1 The initial start-up
Only Viessmann or another trained specialist may put a
newly installed facility into operation for the first time.
Be absolutely sure to follow the instructions in the Assembly and Installation Instructions. No warrenties may be
claimed for damages in cases of initial start-ups carried
out improperly at one's own initiative.
4.2 Operation
4.2.1 Heating up
-
-
4.2.2 Operation
-
First check:
-
Is there enough water in the heating system?
Has the heating system been bled of air?
Are the slide valves open for the heating-system's
forward and reverse flow?
Can enough fresh air get into the heating room?
Empty ash bin.
Are the doors and lids on the burner all closed leaktight?
For safety keep firing and ashipt doors tightly closed.
Press the F1 key "PYROT Wood". The loader modules
will be switched on in the appropriate order. When
there is enough fuel in the combustion chamber, the
entire loader system switches off.
The automatic ignition then takes place. The ignition
process stops as soon as the fire is started.
-
-
-
-
The material is supplied depending on the light barriers
in the metering container and in the combustion chamber, allowing for the residual oxygen.
The primary and secondary air vents change their positions depending on the exhaust gas temperature and
residual oxygen.
Using the setting "Storage Management, Temperature,
Storage, Average", it is possible to keep the facility in
continuous high-performance operation for as long as
possible – with fewer ignitions, better efficiency and
lower emissions.
(Only possible with accumulator option)
When the boiler temperature set is reached, the facility
switches to "Run Auger Empty". When the feed auger
has been run empty, and the exhaust gas temperature
is less than (90°C) 194°F, the exhaust gas fan
switches off and the air vents close.
When the "System Temperature Setting" is fallen short
of, the boiler is automatically started back up.
4.2.3 Switching off
-
Press the F1 key "PYROT Wood". As feedback to this,
"Run Auger Empty" will appear on the control panel.

The battery needs replacing every five years!
Do not disconnect the mains voltage while changing
the battery (do not turn off master switch)!
5.2 The functions of the keys
5.1 General information
The ECOTRONIC facility control system is a decentralised
microprocessor system (CAN-BUS) developed by KÖB
with various modules that are connected by a data transmission line.
Its function
The ECOTRONIC records all the data relevant to operation
and controls the supply of and demand for heat.
Thus the boiler plant is continuously monitored during all
the operating phases and kept within an optimum range in
terms of emissions.

5.4.2 Utility water heater
Function:
-
-
ECO-B1
When the temperature of the utility water drops, it is
reheated by the built-in heat exchanger from the heat
accumulator (hydraulic switcher). The condition for this
is a relevant difference in temperature (choice of control according to temperature difference or fixed temperature).
The heating periods (daily and weekly programmes)
can be set using the integrated timer.
ECO-B2
When the temperature of the utility water drops, it is
reheated by the built-in heat exchanger from the heat
accumulator (hydraulic switcher). The condition for
this is a relevant difference in temperature (choice of
control according to temperature difference or fixed
temperature).
The flow rate of the heating water is controlled by the
return temperature (quantity control). This produces
optimum storage stratification with long-lasting high
temperature on the storage unit flow pipe.

Function (ECO-S3):
(Only possible with accumulator option)
This is used in large solar systems to heat the utility water
in a solar utility water heater (Art. No: WSS-4050) and
for supplying heat to the heat accumulator by means of a
triple control circuit. The first circuit is for heating the domestic water, the second circuit is for heating the heat
accumulator at the back/bottom and the third circuit is for
heating the heat accumulator at the front/top. The heating
storage unit is heated up by an externally situated platetype heat exchanger. On switchover from utility water
heater to heat accumulator, the secondary pump is
switched on, which is then in operation with the solar
pump. For optimised functioning, the flow rate in the secondary circuit has to be adapted to the primary circuit
(e.g. with flow rate gauges in the primary and secondary
circuits).

Cleaning/Maintenance
6.1 Boiler
The heat exchanger, flue pipe, and chimney must be cleaned regularly to remove accumulated creosote and ash. Ensure that
the heating exchanger, flue pipe, and chimney are cleaned at the end of the heating season to minimize corrosion during the
summer months. The appliance, flue pipe, and chimney must be in good condition.
Regular cleaning and maintenance of the boiler system is the customer's most important job for years of trouble-free operation and to obtain the greatest possible output with the best efficiency.
Here the cleaning intervals for chip material are listed with clinging bark – 0.8% ash content. The cleaning intervals may vary,
depending on the fuel, the amount of fine matter and the operating method.
CAUTION – RISK OF INJURY: Before beginning cleaning work, put the facility out of operation. Be absolutely sure to wear
protective gloves, protective eyewear if required and use the cleaning utensils that come with the facility (danger of blowups, burns and getting crushed)!
After approx. 1000 operating hours:
Unplug the plug from the exhaust gas
fan, unscrew butterfly nuts, pull out

-
-
-
-
Operation and maintenance of the compressor (optional) according to the manual that comes with the
facility.
The timer that comes with the compressor is for limiting the running time and should be mounted between
the compressor and the power supply.
When the compressed air system is provided by the
customer, the compressor has to be suited for continuous operation or be secured against continuous operation (e.g. timer for limiting running time).
Continuous operation of the compressor indicates leakage in the air system. Check air supply line and valves
for leakage.
After approx. 300 operating hours (90litre ash bin):
Empty ash bin beneath the de-duster.
IMPORTANT: Never operate the boiler without ash container!

6.2 Installing the displacement rods into the heat exchanger
The displacement rods improve the heat transmission in the heat exchanger and reduce the temperature of the exhaust gas,
thus improving the efficiency of the heating system. They are taken out to clean the heat exchanger tubes and then put back
in.
Insert the displacement rods into the heat exchanger tube with the thick end first. Push until they are flush with the bottom
of the tube. Tolerance +/- 5 mm.
Fig. 1
Flush with
the bottoms
of the tubes
Remove the displacement rods with a pair of pliers, as shown below. The heat exchanger should be cleaned at the intervals
prescribed so that, on the one hand, performance and efficiency are maintained, and on the other, the displacement rods can
be easily removed.

6.3 Feed systems
Control system
When storage facilities for wood are required the wood
should be kept at least 1.5m (5ft) from the heating appliance.
Even when the PYROT is put out of operation for long periods, the power supply to the control system should not
be interrupted (do not turn off master switch).
All the geared motors on the feed systems are maintenance-free.
Why?
-
-
-
-
A change of lubricant and/or oil is recommended every
20,000 operating hours or every three years.
Re-lubricate flange bearings and other lubricating
points regularly with lithium soap grease.
Check chain drives for wear and, if necessary, tighten
them up and lubricate with chain oil.
Check all the bolts to be sure they are snug.
Once a year check the extraction components in the
silo and/or bunker for damage and soiling. Remove any
foreign matter there might be.
Rotary sweep extraction system (AG)
Check and lubricate elbow joints, pivot pins, tension
springs and tension chains. Readjust elbow joints if
necessary.
Inclined extraction system (AP/APS)
Lubricate the gasket between the extraction casing and
the geared motor and universal joint for the auger.
If fuel hopper is installed, do not after equipment in any
way.
May be connected to an existing boiler or solar system.

8 Carrying out disposals
Shutdown
-
-
Pipe-type heat exchanger:
When the PYROT is put out of operation for a long period (such as for summer breaks), be sure to carefully
clean the pipe-type heat exchanger with a steel brush
required.
Disconnect the mains connection to the control cabinet.
-
Close the forward flow and return flow slide valves.
-
Open the drain tap on the bottom of the boiler of the
PYROT and drain water.
7 Shutdown
-
If necessary, first switch off the PYROT using the F1
or F2 key. When the burn-out has taken place, and the
burner has cooled off, turn off the master switch.
CAUTION DANGEROUS VOLTAGE!
Only licensed electrical firms are allowed to disconnect
and dismantle the connection to the electrical network.
IMPORTANT: Never use inflammable lubricants!
Heating boiler
The "intermittent control system" switches the consumer pumps on for five seconds every 24 hours. This
prevents the pumps from jamming during long standstills. This saves on expensive repairs.
Prevent the formation of condensation in the lambda
sensor.
Extend the service life of the buffer battery.
Only heating system installers may drain the boiler and
dismantle the connections to the heating system.
-
Disconnect the forward flow pipe and return flow pipe
from the PYROT.
Instructions regarding transport to a different location
-
-
Prevent high-temperature corrosion when chipboards
are incinerated:
If the heating room is moist or there is any other atmosphere that promotes corrosion (e.g. poor ventilation, residual enamel near the heating room, etc.), after
carrying out the cleaning, also spray the pipe-type heat
exchanger with biodiesel.
If there is a danger of frost, empty the heating system,
following the heating installer's rules, or have anti-frost
agent filled.
The personnel who carry out transports to different locations have to know the dangers involved of accidents that
might arise in doing so and use suitable measures to prevent such from happening.
Instructions regarding waste disposal
Ashes should be stored in covered metal container on noncombustible floors away from combustible material
- Comply with customary laws and regulations on disposing of waste.
- Contract a disposal firm to dispose of and recycle
waste in an environmentally friendly fashion.

A prerequisite for approval is the express permission for such by the public authority responsible. For claims to the warranty according to
Section 11 of our General Terms and Conditions of Delivery, wood fuels have to meet the following conditions. If those conditions are not
met, then approval is possible with restrictions (warranty, maintenance, operational safety) with a written statement by the manufacturer in
reference to the facility.
1) Non-combustible substances contained
No wood fuels may contain any foreign bodies, such as pieces of metal, stones, masonry remnants or plastics. Nor
must the following limits (per kg of dry fuel) for non-combustible substances contained (ash analyzed at a
temperature of 815°C) be exceeded or fallen short of:
Limit
Comparison with untreated forest wood
1.1) Chlorine Cl:
max. 300 mg/kg
10 mg/kg
1.2) Sulphur S:
max. 1000 mg/kg
120 mg/kg
1.3) Total Cl, S:
max. 1000 mg/kg
130 mg/kg
1.4) Ash content, total:
max. 15.0 g/kg
5.0 g/kg
1.5) Alkali oxides in the ash (K2O and Na2O): max. 1.0 g/kg
0.35 g/kg
1.6) Sintering point of the ash:
min. 1000°C approx. 1200°C
Consequence of substantial overstepping of limits (1.1, 1.2, 1.3, 1.5, 1.6):
a) Hot-gas corrosion in the heat exchanger → Special maintenance instructions for heat exchanger
→ Shortened service life of heat exchanger
b) Early sintering and melting of the ash
→ Special maintenance instructions for firing,
→ Increased maintenance costs (firing, boiler door)
If the maintenance instructions are not followed, a process will be created that builds up in a negative fashion with:
→ Cinders change the airflow → Temperature peaks → more slag → etc, until there is fast destruction of the refractory materials
1.7) Additives in remnant and used wood: Free of heavy metals and halogen compound
2) Superfine & dust (wood particles smaller than 1.0 mm)
2.1) Without pre-dryer, max. 10.0% of the total mass; consequence of substantial overstepping of limit:
Temperature peaks → Slag formation → Even higher temperature → etc, to the point of destruction;
→ Special maintenance instructions for firing;
Elevated values are especially critical for remnant wood in combination with elevated values as per 1.1, 1.2
2.2) For forest wood chips with pre-dryer, max 4.0% of the total mass; consequence of substantial overstepping of limit:
→ Moving the exhaust air lines → Special maintenance instructions for cleaning exhaust air line
3) Origin and treatment
3.1) Forest wood and plantation wood (complete trees and trunk wood untreated)
Mature wood from trunks and branches, untreated, chopped as billet wood or chips
3.2) Compressed wood, pellets
Untreated wood with limited bark content, compressed by machine and calibrated
3.2) Increased proportion of bark, tree cuttings from roadside trees (untreated)
Remnants from the forestry and sawmill industries or from conservation of the countryside (elevated ash
content).
3.3) Remnants from derived timber products
Usually a mixture of untreated and treated wood in the form of shavings from processing machinery and chips from choppers that
run slowly. In cases of elevated proportions of dust and/or limited storage volumes, these shavings are compressed into briquettes.
3.4) Used wood
This is essentially untreated wood that has been used prior to its energetic utilization (e.g. pallets). It is reduced
in size by shredders for thermal utilization. The metal parts have to be removed afterwards (by magnetic separators).
4) Particle size: adjustment of the conveyor augers
4.1) G30/G50 chips from untreated wood:
made by fast-running and cutting tools;
max. coarse fraction
with cross-section
and length
G 30
of 20% max.
3 cm²
max. 8.5 cm;
G 50
of 20% max.
5 cm²
max. 12 cm;
Required cross-sections of the loading: depends on the boiler output:
up to 150 kW
up to 500 kW
from 500 kW
Conveyor auger
D
min. 12 cm;
min. 15 cm;
min. 20 cm
Drop cross-section
A
min. 175 cm²
min. 300 cm²
min. 600 cm²
4.2) Chips not from the forest; origin as per 3.2, 3.3, 3.4; briquettes, origin as per 3.3
Size essentially as per ÖNORM M 7133 G50, additionally, however:
- Fraction of one-offs max. 5% with cross-section of max. 5 cm² up to a length of max. 16 cm
- Frayed surface by chopping tools (shredders) or slow-running choppers
- Briquettes, diameter max. D 60 mm (hydraulic compressors, pressure geared to loading system)
Conveyor augers diameter min. 20 cm; drop-off route, rotary valve cross-section min. 600 cm2
Consequence of overstepping particle size:
- Extra expenditures for correcting malfunctions
- Shortened service life of the conveyor augers and drives

6) Maximum water content allowed, W, (percentage by weight of the total mass)
The maximum water content allowed in the fuel when entering the furnace should be taken from the spec sheets for
the furnace series. With a pre-dryer installed between the furnace and the fuel storage site, extra water content can
be in the fuel stored (see specifications in reference to the order). The water content influences the maximum
furnace output possible, the heat emission required to the pre-dryer and thus the maximum heat emission possible
to the consumers.
7) Other information
7.1) Ash and cleaning
Untreated wood without bark has a proportion of ash less than 0.5% of the fuel mass supplied. All the
specifications regarding cleaning involved are based on untreated wood with bark attached with an ash amount
of 0.8%. The cleaning and maintenance involved for other wood fuels should be adapted according to the
amount, the specific weight and the behavior of the ash.
7.2) Changing fuels
A great change in fuel quality, such as bulk density, water content, dust proportion or ash content might make a
manual correction of the firing parameters necessary (see Operating Manual).
8) Non-woody fuels from biomass
Non-woody fuels from biomass, such as needles, foliage, grain, straw, fruit pits, etc, are usually unsuited as fuel for
trouble-free operation and thus are not approved.
9) Information documented
The installation instructions contain the information required according to the subject boilers have been tested and examined in accordance
with:
